The DC DC Voltage Converter is a compact automotive power module designed to keep 12V/13.8V loads running reliably. It automatically buckboosts a wide input range of 840V to a steady 13.8V output at up to 3A, ensuring consistent performance for devices in vehicles even as the electrical system voltage fluctuates. CE and RoHS certified, this module is built for automotive use and alignment with modern safety and environmental standards. Key benefits Stable 13.8V output from a wide 840V input range, ideal for powering 12V/13.8V devices in cars. Automatic buckboost regulation maintains the required voltage as the vehicle electrical system changes during starting, idling, or charging. Compact power module designed for easy integration into automotive installations and projects. Supports up to 3A of continuous current, suitable for multiple devices or higher demand loads within a typical 13.8V system. CE RoHS certified, providing assurance of safety and environmental compliance. Key attributes Functionality: DCDC converter with automatic buckboost operation to deliver 13.8V at up to 3A.
